This column introduces new institutional measures for 17 EU candidate countries since 1997 to explore whether deep integration helps the build-up of state capacity. Estimates highlight the relationship between judiciary capacity and bureaucratic independence as the key engine behind state capacity-building engendered by the prospect of EU membership.

Economics, and economists, are often accused of insularity and hubris, and of talking primarily to themselves in their research. This column uses a recent analysis of citations to and from other disciplines to show that this is no longer the case. Economics papers increasingly cite non-economic research, and other disciplines cite economists more often too. The data suggest that the rising quantity and quality of empirical research in economics has increased the relevance of the field to non-economists.

Separating cause from effect is notoriously difficult when it comes to gentrification and neighbourhood amenities, including public safety. This column exploits the sudden ending of a rent control regime in Cambridge, MA to examine whether and by how much gentrification affects crime. In the years immediately following the end of rent control, crime fell significantly more in neighbourhoods that had been heavily rent controlled. However, those neighbourhoods also saw the highest turnover in occupants, suggesting that incumbent renters of in these areas were priced out of their properties and thus missed out on the benefits from gentrification.

Venture capital firms use a variety of accumulated resources to inform their investment activities, but do the rely solely on their own resources or do they employ other firms’ resources to complement their own? This column examines the pattern of co-investments among venture capital firms and discusses the economic implications. Past experience of co-investments increases the likelihood of future co-investments among firms when the returns from these past co-investments were high, and also when the jointly invested venture business companies experienced greater growth after an IPO.
